Energy can get wasted through several means. One of the most obvious ones is friction. However, entropy also increases - and energy therefore gets wasted - in other ways; for example, when there is a heat transfer between two objects that are at different temperatures; when eddies are produced in a water current (or electrical current); when electrical current gets converted to heat in a resistance; and through several other means. Quite often, the intention of an energy transformation is to produce one type of energy (for example, light in a light-bulb); but additional (undesired) types of energy are produces as well, quite often heat.
In any energy transformation energy is preserved.
friction, heat, ... any form of energy (work) it produces, that doesn't serve the main purpose of the machine.
A change from one form of energy into another is called energy transformation.
Energy transformation
The radio signal itself, of course, is not an energy transformation - energy transformation means that energy is changed from one type to another. There is an energy transformation when the radio signal is created, and another one when it is absorbed.
In any energy transformation energy is preserved.
It is Chemical Energy because there are some chemicals stored on the bread which you eat.
In any energy transformation energy is preserved.
Energy Transformation is when energy changes from one form to another. :)

energy transformation is ruled by energy conservation. For example, potential energy may transform to kinetic energy but the sum of both remains constant before and after transformation.
